I needed to find a use for my old Creative Zen media player, so here it is. Print all of the pieces and assemble the case. Use hot glue to hold the Zen in the case. I used a pair of old headphones and glued the speakers on the back. I wired the speakers directly to the circuit board of the Zen to avoid the headphone jack. The "buttons" and "screen" pieces are printed thin enough so that they are flexible and the Zen buttons can still be accessed by pushing on the front of the screen.
I'll post a link to a complete build log soon.
